These deposits are also called segregation or accumulative deposits chromium, titanium, and iron deposits The kimberlite diamond pipes of Eastern Siberia and South Africa are original early magmatic deposits Third, when gas-rich magma crystallizes the mineral substance may concentrate in the easily fusible residual melt and during the ensuing solidification form late magmatic or ....
NATIVE PLATINUM Pt - Amethyst Galleries Mineral Native platinum is an exotic mineral specimen and an expensive metal Unfortunately, well formed crystals of platinum are very rare and the common habit of platinum is nuggets and grains...
Pegmatite minerals, such as beryl, cassiterite, lepidolite, scheelite, and niobium-bearing minerals occur chiefly with granitic rocks It is thus seen that deep-seated mafic rocks are the associates of most of the magmatic mineral deposits This indicates a genetic relationship with the early magmatic history of associated rocks...

In mineral deposit Magmatic cumulat Magmatic segregation is a general term referring to any process by which one or more minerals become locally concentrated segregated during the cooling and crystallization of a magma...
Abstract A magmatic ore deposit is an accumulation of magmatic minerals Some of these minerals are extremely rare and almost never encountered in common rocks, an example being alloys of the platinum metals other minerals, such as magnetite, are common and can be seen in many thin sections...

Some of the commonly formed mineral deposits formed due to magmatic segregation are iron, granite, aluminum, diamond, chromite, and platinum The different temperatures and basicity zones that prevail in magma cause the concentration of the ore, thereby resulting in the segregation of various minerals...
